As the Hawkesbury region endures a severe heatwave, health experts are urging residents to prioritise hydration and take precautions to avoid dehydration and heat-related illness.
With temperatures soaring above 35 degrees and expected to reach near 40 degrees over the coming days, doctors and health officials remind the community that staying hydrated is essential to coping with extreme heat.
According to recent advice from health authorities, most adults lose around two to three litres of water each day through normal bodily functions, and this increases significantly in hot weather due to sweating. Drinking plenty of fluids regularly is the best way to stay hydrated.
Dehydration, however, can be sneaky. People may not always feel thirsty even when their bodies need water. Common symptoms of dehydration include dizziness, dry mouth, headache, and dark-coloured urine. Residents are encouraged to watch for these signs, especially vulnerable groups such as the elderly, young children, and those with chronic illnesses.
Health experts emphasise that the temperature of the water you drink does not significantly affect how well it cools your body. Instead, the volume of fluid intake is what matters most. Plain water remains the best choice for hydration, while sugary drinks, caffeine, and alcohol can actually contribute to dehydration.
Hydration is only one part of staying safe during the heatwave. Avoiding strenuous activity during the hottest parts of the day, finding shade or air-conditioned spaces, and limiting time outdoors between 11am and 3pm are equally important.
GP Dr Michael Wright, President of the Royal Australian College of GPs, urged the community to take the heat seriously.
“Heatwaves can be deadly, particularly for older people and those with existing health conditions,” Dr Wright said. “Please ensure you drink plenty of water, stay indoors during peak heat, and check on friends, family and neighbours who might be vulnerable.”
With the heatwave forecast to continue, community health officials say spreading awareness and taking simple precautions can save lives.
